asp.net 5.0 project.json中RavenDB.Client引用的问题

Question

I'm trying to build a RavenApiController with the new ASP.NET 5.0 (aka Asp.Net vNext) stuff and can't seem to get the RavenDB.Client references to work at all.

The error I get is

Error CS0246 The type or namespace name 'Raven' could not be found (are you missing a using directive or an assembly reference?) SharedIO.ASP.NET Core 5.0 RavenApiController.cs 3

My project.json is as follows

{
"webroot": "wwwroot",
"version": "1.0.0-*",
"exclude": [
    "wwwroot"
],
"packExclude": [
    "**.kproj",
    "**.user",
    "**.vspscc"
],
"dependencies": {
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta2",
    "Microsoft.AspNet.Diagnostics": "1.0.0-beta2",
    "Microsoft.AspNet.Mvc": "6.0.0-beta2",
    "RavenDB.Client": "3.0.3599",
    "SharedIOModel": "1.0.0-*"
},
"frameworks": {
    "aspnet50": {},
    "aspnetcore50": {}
}

}

The code for RavenApiController.cs which fails to build on the third line begins as:

    using System;
    using Microsoft.AspNet.Mvc;
    using Raven.Client;
    using Raven.Client.Document;;

    namespace SharedIO.Controllers
    {
        [RequireHttps]
        public abstract class RavenAPIController : Controller
        {
            public IDocumentStore Store
            {
                get { return LazyDocStore.Value; }
            }

Totally stumped.

For what it's worth intellisense seems to be able to find the reference just fine and I don't get an error until I actually 'build solution.

Also Intellisense shows me that (for example) Raven.Client.Document.IDocumentStore is 'Available' in ASP.NET 5.0 but 'Not Available' in 'ASP.NET Core 5.0'.

The problem is that you referencing RavenDB.Client in the top level dependencies node in project.json . That means that those dependencies are applicable to both Desktop CLR ( aspnet50 ) and CoreCLR ( aspnetcore50 ).

When you build an ASPNET 5 project, all configurations are built, not just the "active" one. Mostly sure RavenDB.Client works only with the Desktop CLR so move it under a dependencies node under that configuration.

"dependencies": {
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta2",
    "Microsoft.AspNet.Diagnostics": "1.0.0-beta2",
    "Microsoft.AspNet.Mvc": "6.0.0-beta2",
    "SharedIOModel": "1.0.0-*"
},
"frameworks": {
    "aspnet50": {
        "dependencies" : {
            "RavenDB.Client": "3.0.3599",
        }
    },
    "aspnetcore50": {}
}

Then you might have to either use some conditional blocks in your code ( #if ASPNET50 ) or remove CoreCLR all together.
